EIGEN8
Jack Altman's EIGEN8, launched 2022, is a San Francisco single-family office investing operator-led capital into enterprise, AI, and climate companies.
EIGEN8
EIGEN8 was established in 2022 as the investment vehicle for Jack Altman, who previously co-founded and led Lattice as CEO, scaling the people-management platform to a $3B valuation. The wealth origin is directly tied to Altman's own operating career in enterprise SaaS, giving the office a distinct lens on early-stage B2B software. Unlike some multi-generational family offices, EIGEN8 was built to deploy first-generation tech wealth, with a posture shaped more by operator instinct than by institutional asset allocation models. The firm runs a concentrated strategy split between early-stage venture, growth equity, and opportunistic private equity buyouts. Asset classes include direct venture capital, private equity co-investments, and select liquid positions in public tech equities. EIGEN8 targets founders who are building enterprise infrastructure, applied AI, and climate resilience companies. Confirmed positions include AngelList, Pilot, and Slope (per public record, 2023–2024). The geographic mandate is primarily US-based, with particular density in the Bay Area and New York startup ecosystems, though the firm will follow exceptional founding teams into Latin American and European markets. Operating from San Francisco, EIGEN8 keeps a small internal team by design. The firm does not publicly disclose headcount or total deployment, but its activity pattern suggests annual deployment in the tens of millions. A notable structural feature is the office's proximity — both geographic and philosophical — to HyperAlpha, the invite-only founder community where Altman participates alongside other repeat entrepreneurs. This network provides EIGEN8 with a proprietary sourcing channel into competitive early-stage rounds. In August 2024, Altman joined the board of Slope, a B2B payments infrastructure company, reinforcing the firm's model of high-conviction board work over spray-and-pray portfolio construction. EIGEN8's genuine structural differentiator is its identity as an active single-family office that operates with the decision speed of a solo GP. Unlike family offices that hire an external CIO to gradually shift from a founder's concentrated wealth into a risk-parity model, EIGEN8's portfolio remains a direct expression of Altman's own investment judgment and network. This keeps governance flat and investment committees effectively absent, enabling same-week term sheets for the right founding teams — a posture that competes directly with top-tier seed funds rather than other family offices.

Frequently asked questions
Who runs investment decisions at EIGEN8?
Jack Altman, the founder and managing partner, makes all final investment decisions. He operates EIGEN8 as a single-family office backed by his own capital from the Lattice exit, with no external limited partners or investment committee to slow decisions. The office does not publicly list any other investment professionals, indicating Altman retains sole discretion on capital allocation.
How does EIGEN8 source proprietary deal flow?
The firm's primary sourcing advantage comes through HyperAlpha, the invite-only community of repeat founders where Altman is an active member. This network provides early visibility into companies being started by operators who have previously built and exited businesses. Additionally, Altman's own tenure as a founder-CEO in the HR tech space gives him direct relationships with other founders who often approach him for their first institutional capital.
Is EIGEN8 structured as a single family office or does it operate more like a venture firm?
EIGEN8 is legally structured as a single-family office but operates with the posture and speed of a solo-GP venture firm. It deploys exclusively Jack Altman's personal capital, not outside LP money. However, the office's investment pattern — concentrated seed through growth-stage checks into B2B software, direct board involvement, and operator-first sourcing — is behaviorally closer to a venture capital firm than a traditional institutional family office.
Which sectors does EIGEN8 explicitly avoid?
EIGEN8 does not publicly disclose a formal exclusion list, but its portfolio pattern shows a clear avoidance of consumer social media, ad-revenue-dependent marketplaces, and hardware-heavy deep tech. The office's investments are concentrated in enterprise infrastructure, applied AI, payments, and climate resilience — all sectors where Altman's own operating background gives him a direct line of sight into the founder's challenges and the company's unit economics.
How is EIGEN8 related to Altman Capital or any other family office in the Altman family?
EIGEN8 is Jack Altman's single-family office and operates independently from Altman Capital, the family office run by his brother Sam Altman. The two offices have different investment mandates, portfolio concentrations, and sourcing channels. No shared investment vehicle or pooled family capital has been publicly disclosed between them.
Where does the underlying wealth come from?
The capital deployed by EIGEN8 originates primarily from Jack Altman's liquidity during his time at Lattice, the HR technology company he co-founded and led to a $3B valuation. Altman served as Lattice's CEO until 2022, and the enterprise's growth — alongside secondary share sales and broader exposure to the technology sector through his family — forms the wealth base behind the office's current investment activity.
Does EIGEN8 participate in fund commitments or only direct deals?
EIGEN8 primarily makes direct investments into individual companies, often leading or co-leading seed and Series A rounds. The office has not publicly disclosed committing capital as a limited partner to other venture funds, though it may hold legacy fund positions from before the office's formal founding in 2022. The stated preference is for board-level, high-conviction direct bets.
